EOS Bodies / Re: Downgrade to crop
« on: December 03, 2012, 09:20:35 AM »I'm in the same situation. I still have a 350D (yes they still exist), and plan to ugrade in the near future. In the race are the 6D, and the upcoming APS-C models (70D? 7D MkII?). I only shoot as an amateur, and I'm really asking myself if it is worth to upgrade to a FF (6D).Same boat. If I could only find a 24-105 f/4 equivalent for my 60D, I would sure hold it for now and upgrade to FF when(ever) I start making money from photography. I would stick to my 50 1.4 and get a 35 1.4 (or a 28 1.8?) and an 85 1.8, and have fun!
DOF is one point, but I think that the DOF is already quite shallow on a APS-C with a decent lens; especially when you are close to the subject. There is a range in distance where the FF would be helpful, but is it worth the money?
Reach; this is only a question of money. Are you willing to pay twice as much for a lens, to get the same reach with a FF, as you would have to with a APS-C? Croping is not an option; why should I pay for Sensor-area I do not use?
IQ/Noise. This is the biggest issue. But living with 8.5MP for 7 years showed me, that the quality of an Image is not measured in ISO, Noise or dynamic range. Sure, Images from a FF look really nice. I compared the pictures from FF to APS-C on The-Digital-Picture.com, and the the FF looks much better (no surprise), but then I looked at the comparison tool at dpreview and there the verdict was not so clear anymore. Sure FF is always better, but by how much?
If you are a pro, then it is easy to deceide, but as an amateur I'm still asking myself if it is worth to upgrade.
The reach only matters if your output demands it. A FF image cropped to the same FoV of an APS-C sensor will have essentially the same IQ - the only thing you're really giving up is megapixels. So, if 7-8 MP is sufficient (which it is for web, slideshows, and prints up to ~12x18" - and I suspect that covers most people's needs), then a cropped FF shot will do just as well as an uncropped APS-C shot.

, so really the rest of the spec list is a moot point
